How do you stop organize by thread in iCloud mail

Hi Stoporganizebythread,

Thank you for using the Apple Support Communities! It looks like you want to change settings for viewing and organizing threads when you're using iCloud Mail on the iCloud website. Is that right?

In general, you'll find any available settings by clicking the gear at the top of the sidebar when you're viewing mail on the iCloud website. However, there is not an option to change thread organization, and if that's a feature you'd like to see, you can always send your suggestion to Apple with this link: Product Feedback - Apple

Have a great day.
